Resume Keywords & ATS Optimization

Applicant Tracking Systems (ATS) are software that 99% of Fortune 500 companies and 75% of mid-size companies use to filter resumes. Popular systems include Workday, Greenhouse, Lever, iCIMS, and Taleo. They parse your resume into structured data, match keywords against job requirements, and rank candidates before a recruiter ever sees your application.

The best keyword source is the job description itself. Read it carefully and identify: required skills (usually in a "Requirements" section), preferred qualifications, tools and technologies mentioned, and industry-specific terminology. Use our built-in Keyword Matcher tool: paste the job description and it will highlight which keywords your resume already contains and which ones you're missing.

Distribute keywords naturally throughout your resume: professional summary (2-3 key terms), work experience bullets (in context, not just listed), skills section (exact matches), and certifications section. Don't stuff keywords — ATS systems are sophisticated enough to penalize unnatural repetition. Each keyword should appear 1-3 times maximum.

ATS-friendly formatting rules: Use standard fonts (Arial, Calibri, Times New Roman). Avoid tables, columns, text boxes, and images. Use standard headings: "Work Experience" not "Where I've Made an Impact." Save as PDF (most modern ATS handle PDFs well). Don't put critical information in headers or footers. Use simple bullet points (•), not fancy symbols.

Biggest ATS mistakes: using creative resume templates with columns and graphics (they break parsing), saving as .docx when PDF is accepted, using abbreviations without spelling them out (use "Search Engine Optimization (SEO)" first, then "SEO"), putting contact info in headers (many ATS can't read headers), and submitting without tailoring keywords to the specific job post.
